Experience with MSI PRO Z790-P or MSI PRO Z690 DDR5 Motherboards?

What think you about this?

Have the new hardwares more backdoor?

I read a comment of @thoring_around And i want to know what the people thinking about that. He said: “if the hardware is new and it’s produced in one of the western countries(not limited to them tho), no matter what you do - you have hardware backdoor” (If it’s true, than the ASUS KCMA-D8 Motherboard better than the MSI PRO Z690-A.)
